What is Oxygen Concentrator? How it works, know everything here!

New Delhi: Our country is reeling from the second wave of the pandemic. In such cases, there has been an alarming increase in the number of active cases due to the increase of infections. As a result, our public health infrastructure is under stress and the demand for oxygen concentrators has increased.

So let's know exactly what oxygen concentrators are, when they are needed and how they are used or not-

Need of Oxygen concentrators:

To survive we need a constant supply of oxygen, which flows from our lungs to various cells of the body. Covid-19 is a respiratory disease that affects our lungs and can cause oxygen levels in the body to fall to dangerous levels.

In such a situation, in order to increase the oxygen level in the body to a medically acceptable level, we need to give therapeutic oxygen therapy using oxygen.

How does it work?

Oxygen levels in the body are measured as 'oxygen saturation' which is abbreviated as 'SPO-2'. It is a measure of the amount of hemoglobin that carries oxygen in the blood. Oxygen saturation in the artery of a healthy person with normal lungs is 95% -100%.

According to the World Health Organization's training manual on pulse oximetry, if the oxygen saturation is 94% or less, the patient needs to be treated quickly. If the saturation falls below 90%, it is considered a medical emergency.

We know that the atmosphere air contains about 78% nitrogen and 21% oxygen. The oxygen concentrator is a simple device that does exactly what its name expresses. These devices take air from the atmosphere and filter nitrogen from it and throw it away and increase the oxygen density.

These oxygen concentrators supply oxygen needed for the body in the same way as oxygen tanks or cylinders. Through a Cannula, oxygen mask or nasal tubes. The difference is that, while cylinders need to be refilled frequently, oxygen concentrators can work 24 hours a day, seven days a week.
